NUT-LOCK SPZECIPICA'IION forming part of Letters Patnt Nq. 299,755,dated June 3, 1884. Appication fileddil[arch 1, 1884. (No model.)

T0 aZZ whom it mdy concern Be it known that I, ROY Donsonof Centraltownship, St. Louis couniy, Missouri, have made a neW and usefulImprovement in Nut- Locks, of whichthe following is a full, clear, andexact deseription, referenee being had to the annexed drawings, makingpart of 'this speeification, in which Figure 1 is a side ele'vation of arailwayjoint having the improvement; Fig. 2, a, side elevation of thelocking-rod; Fig. 3, a crossseetion 0n bhe line 3 3 of Fig. 1, and Fig.4 a cross-section on the line 4 4 of Fig. 1.

The Same letters of reference denote the same parts.

T his invention eonsists in employing, in conneetion with two fish-bars,one of whieh is pro vided with lips, a spring-locking r0d headed ab oneend and bent Or crooked at the other,

substantially as hereinafter deseribed, and designated in the claim.

A A, Fig. 1, represenb the opposing rail ends of & railwayjoint. Brepresents the fish-bar upon one side of the rails, and 0 represents thefish-bar on the opposite side of the rails.

"D D represei1t the bolts, and E E represent 3, 41hat is, he springlocking-rod, when in position, rests in and bears down upon the 1ips 0 0and bears upward against the nuts E E. 'Ihe locking-rod thereforeoperates to prevent the nuts from unscrewing upon the bolts.

In operaton, the nuts E E are serewedup and the bolts D D are tightenedin the ordinary mann'er, after whieh the Spring locking-rod is insertedendwise into the space between the lips and the nuts. '1he r'od at oneend is pro vided with a suitable head, f, and at the other end, f, iserooked slightly, substantially as shown in Figs. 1, 2. In this mannerthe1oekingrod, while serving 'IJ0 hold the nuts E E in place, in turn isheld in position by the nuts and lips, and is prewnted from moving endwise out of p1ace by the head f and the erook f. The locking-rod is madeof spring meterial, to enable the end f te yie1d slight1y as is passingthe nuts and 1ips, and then t0 spring downward, substanbially as shown,after it has passed the end of the fish-bar.

Any suitable method may be adopted in attaching the 1ips 0 0 to the body0 of the fishbar-that is, they may be riveted or welded to the fish-bar;or, in making t-he fish-bar, the lips may be an integral part thereof,and afterward shaped into positioi1.

A modificabion of the construebion shown is attaehingthe 1ips to theupper edge of the fishbar in place of 120 the 10wer edge, s0 as to eausethe spring loeking-rod t0 bear downwardupon the upper sides of the nutsE E, instead of upward against the under side of the nuts, as shown.

I claim- The combination of the rails AA, the fishbar B, the fish-bar O,havng 1ips c 0, the bolts D D, the nuts E E, and the spring locking-rodF, having the head f and the crooked end f substantially as and for thepurposes described.
